+Twitter Timeline on Main View
+---------------------------
+
+This is a feature to include a twitter feed that displays most recent tweets
+of a (determined) twitter account (accessed via Twitter API).
+If you chose to use it, the feature gets included in `home/index` of
+LEAP web app (as part of the main view).
+
+* Create Twitter Application on https://apps.twitter.com/
+ * Visit https://apps.twitter.com/ and log in with the twitter account you want to use
+ * Make sure you have a mobile phone number registered with your account to be able to proceed
+ * Choose the option to `Create New App`
+ * Fill in Application Details and Developer Agreement and `Create your Twitter application`
+ * Choose the section "Keys and Access Tokens" to get your consumer key and consumer secret
+ * Optional: Go to section "Permissions" and change the "Access" from `Read and Write` (by default) to `Read only`
+ * Have your consumer key and secret by hand for one of the next steps
+
+* Activate the feature within your local LEAP Web Application
+ * If not already existing create a secrets-file in /config with the name secrets.yml (`/config/secrets.yml`)
+ * Secrets-file should contain the following, make sure its in YAML: {"development"=> {"twitter"=>{"enabled"=>false, "twitter_handle"=>"", "bearer_token"=>"", "twitter_picture"=>nil}}, "test"=>{"twitter"=>{"enabled"=>false, "twitter_handle"=>"", "bearer_token"=>"", "twitter_picture"=>nil}}}
+ * To have your bearer token created, run script in terminal being in the file of leap_web: `script/generate_bearer_token`
+ * To have the script run properly you have to add before running: `--key your_consumerkey --secret your_consumersecret`
+ * Add also `--projectroot your_projectroot --twitterhandle your_twitterhandle` as well to not have manually put the data in your secrets-file
+ * The full command looks like this: `script/generate_bearer_token --key your_consumerkey --secret your_consumersecret --projectroot your_projectroot --twitterhandle your_twitterhandle`
+ * If you didn't give all your information to the script, had a typo or want to change anything else, please do so by finding the secrets-file at `/config/secrets.yml`
+ * Make sure that the correct twitterhandle and bearer-token is included
